[Sony Xperia Miro, Tipo (Dual), J, E] sankuk28:
Hi,

I recently installed FXP 207 CM10 on my xperia J and now I would like to temporarily go back to a stock rom.

I've installed Flashtool 0.9.10.1 and the flashmode drivers (from C:\Flashtool\drivers). Then I follow normal flashing process and everything seems to go smoothly except that the progress bar stays at 0% (no errors). This seems similar to http://xdaforums.com/showthread.php?t=2089275 except it's with an Xperia J and unfortunately problem remains when in PTP.

Here's the Flashtool log:

What I've tried so far:

- Debug mode and unknown sources activated

- PC companion is not running in the background

- Tried with MTP and PTP mode

- Tried with 3 different cables

- Tried different usb ports (front and back)

- Tried leaving my finger on the volume down button during the whole process

- Tried on a Win 7 64 and on an XP sp3 32 (The win xp is a virtual machine but the issue is exactly the same)

- tried with 3 different ftf files (1x .28, 1x .18 and 1x .7.5)

- Bootloader was unlocked using Sony official method

- in http://xdaforums.com/showthread.php?t=2124168&page=4 satan89 advised to first flash a Rom based on stock Rom ( and that did the trick for a Tipo), but is there such a rom for the xperia J ? I looked but couldn't find one :(

- I tried after flashing official kernel with fastboot first but same issue afterward

- I Installed AOKP (KXP) and tried again but still 0%

I really don't know what to try anymore, do you have any ideas of what could cause the issue?
